The ICS M4A1 Tubular RAS Series AEG is ICS's take on a tuned-up M4 rifle. The ultra-light CNC aluminum free float tubular rail system comes with small rail sections which can be placed along any of the slotted sections for a user-customized rail. Lights, lasers, cameras, grips, and more can be mounted anywhere you want on this RAS system! As a front-wired AEG, the battery is also stored within the rail system. Like many ICS AEGs, this gearbox is split for easy maintenance and quick spring changes making this a great field and CQB rifle. Also included are the ICX CXP style flip up sights. The CXP sights are very easy to operate and can easily be deployed or folded down when necessary. The stock is an adjustable 6-position classic carbine stock with sling slots. The metal rotary-style hop-up unit is easily accessible and adjustable when the charging handle is pulled back.
